Thanksgiving

I was away working last weekend, so I wasn't really thinking of Thanksgiving as a holiday. I usually work right through October, so a proper Thanksgiving celebration only happens by chance. Sometimes a little late, like the one I had this year. But with or without the dinner, I'm still thankful for things that happened and those that didn't.

Things happen and things don't. Whether they happen or fail to because of our own skills and planning, because of stochastic processes, or because of an omnipotent being, I am grateful when the right things happen and the wrong things don't. Neither history, nor science, not even religious texts seem to indicate that gratitude or the lack thereof has great influence on what happens and what doesn't, but I still have gratitude. The engines turned when I needed them to. The electricity flowed when I depended upon its service. The ice and the air and my wings did not interact in a way that had a disastrous effect on my flight. Over the years, the malfunctions that have occurred in flight did so after sunrise, within single-engine fuel range of a usable airport, once I was clear of IMC, when I had sufficient altitude, or before I was too tired. I saw what I needed to, and am surrounded by those who look out for me. I am grateful.

Also, you will find it hard to convince me that there is a better way to eat leftover turkey than cold, with my fingers, while standing in front of an open refrigerator.

P.S. to foreigners: Thanksgiving is a post-harvest festival that Canadians celebrate on the second weekend of October. It's not a public spectacle or a commercial event (for places other than grocery stores), just something you do in your home. People with normal jobs get a day off work on the Monday, but family or groups of friends will get together on any of the weekend days for a meal, usually involving roast turkey and seasonal vegetables, especially squash. If you're crafty you can score two or even three turkey dinners over the weekend, and everyone eats turkey sandwiches, turkey soup and turkey salads for a week afterwards.

Battery of Battery-Related Thoughts

I walked all over town to find a 386/301 battery for my IFR timer and a couple of AAAs for my pulse oximeter. Who knew there could be so many different sorts of small round batteries. When buying devices, it's worth including battery availability in the comparison between brands. Everything in aviation should run off AA batteries. I carry a charger and a little pile of spare rechargeables so that when my headset battery cops out, or my flashlight isn't bright enough, I can swap them out.

Mark that against the Bose A20: the batteries are trickier to change in flight than for LightSPEED. They didn't intend you to change them in flight. They have an elaborate system of green and amber flashing lights designed to tell you your battery health and give you a chance to change them before the flight. These don't work with rechargeables, because of their square power profile: they work fine until they are almost dead then drop off to nothing too fast to give a warning. Bose tells you not to use rechargeable batteries for this reason, but I'm not leaving a trail of mercury all over the country for the convenience of flashing lights.

I keep my spare and used batteries straight in the cockpit using a pair of little plastic boxes, one red and one clear, that hold for AA batteries each. I was using it in the north and my favourite captain asked me where I got it. I didn't remember exactly, but told him I'd get him one, and I didn't, but I had to leave before I gave it to him. I asked for his postal address to send it to him, but then he had to leave, and the e-mail I had for him stopped working, but I kept the box all this time. Last time I was packing, I couldn't find my box, so I 'stole' the one I'd been saving for him, but I tell you, if you're reading this, you who forgave me for ripping the REMOVE BEFORE FLIGHT streamer off the engine plug on my first morning at work, send me your address and I will be honoured to send you one.

I have to plug the computer in to use flight simulator programs. The battery runs down too fast otherwise. When I'm flying my toy flight simulator, sometimes the panel lights spontaneously turn off, and I have to cycle the nav lights to put them back on again. Bug or feature to make the whole thing as inscrutably unknowable as a real airplane?

If you thought that last thought was disconnected, how about this one: Originally the forest moon of Endor was supposed to be populated by Wookiees, not Ewoks (wook-ee/ee-wok: original, eh?) but George Lucas decided that since the Wookiee Chewbacca was clearly proficient with advanced technology (i.e. he was pilot and mechanic of the spaceship the Millennium Falcon and also repaired the damaged android C3PO), it would be confusing to show the Wookiees with a primitive, "stone age" culture on Endor.

That's stupid. That's stupid enough to make me angry. That's racist 'logic'. That's the logic that didn't let women run marathons, because they never had. You don't have to be a whiny white moisture farmer with exceptional midichlorians to study and learn things, and it is perfectly possible to learn things that your parents didn't know. You'd have to be keen, and have some aptitude for the subject to make up for the not having the experience of growing up with technology, like Anakin building his own robots and podracers, but there's no reason Kashyyyk couldn't produce competent pilots and mechanics.

You may think this post has gone entirely into deep space, but I'll bring it home by examining Star Wars stored power technology. The Death Star had a massive generator, and no fuel tanks, but the society had batteries, power converters, power couplers and other means of transferring, transforming and transporting energy. I wonder if Han Solo ever had to walk all over Mos Eisley looking for the right sort of power cell for his blaster.

Don't Let It Bug You

Breakfast includes a beautiful green curry soup with bean sprouts, banana flowers and shredded green papayas, then we jump on the bus. It's a modern coach, air conditioned with good legroom. There's a jumpseat that can fold into the aisle between each pair of seats, but we're not overloaded and everyone sits in regular seats. Except for the occasional cockroach that wanders down the windowsill.

We've chartered the bus to pick us up at our hotel, but it isn't an exclusive charter for us. It stops at the depot and some other people board. The bus station looks like a bus station anywhere, quite clean and modern. Ladies with trays of baguettes on their heads mill around outside the bus selling snacks. Once we're underway again a TV on the bus plays a Bollywood style musical romance movie, or maybe it's music videos, with Khmer subtitles

I'm sitting next to a skilled photographer with an expensive camera and she is reviewing some of the pictures she has taken, to see which she will keep. I comment that the yellow rectangle the camera viewer screen puts around the images makes them look like they are from National Geographic. "The whole country looks like National Geographic!" she responds. "You just point your camera anywhere and instant interesting picture." She gives me some photography tips. It's mostly about being in the right place at the right time and looking to see what the camera will see. The human brain is so good at filtering what the eye sees, that as a beginning photographer you can fail to notice something blocking the middle of the shot, tinted windows, undesirable backgrounds, and the like.

I could describe the whole Cambodian experience in ten photographs, none of which I managed to take. At each occasion it was too dark, too quick, too far away, an impolite thing to do at that moment, my battery was dead or there was simply no vantage point for the photograph.

  • an inverted whole pig carried on the back of a motorcycle already carrying two people through the Angkor jungle
  • a woman lifting up a basket, seen just at the moment she is starting to pour freshly harvested rice onto a mat to dry
  • a hundred metres later down the road, a boy sitting in the dirt, pouring dry sand out of a container using exactly the same motion as the woman
  • the look on the woman's face as she received the quilt symbolic of her new home
  • children playing rock paper scissors to determine who goes first at hopscotch
  • two guys in old-fashioned FDR-style wheelchairs, rolling along a busy Phnom Penh street, not crossing the street, just two more wheeled vehicles in a street choked with traffic ranging from bovine to Lexus SUVs
  • A bicycle with one person riding and another sitting on the back, ponying a second bicycle alongside and holding a broken bike chain
  • boys swimming in a muddy pool on the edge of a rice field, with the water buffalo they are tending
  • a blonde woman with a backpack, just alighted from a bus in Phnom Penh, utterly besieged by tuktuk drivers, vendors, many holding signs advertising their services

We flashed passed a hundred scenes that I tried to remember or photograph or write down and then midday pulled into a little town with a café. Most people went into the café. I wasn't that hungry because I had eaten the so-so meat pastries in the lunch box they handed out on board, but I smelled something very good, a smoked fish smell and followed my nose across the street in another direction. The smoked fish were, well smoked fish, but they were dried out completely and sold in quite big bundles, so not appropriate lunch food. Then I spied something else that most people wouldn't consider appropriate lunch food, but that I knew was well into "come here, you have to see this" territory. I rushed back to the café to tell my fellow voyagers, "They're selling deep-fried tarantulas across the street!"

The same vendor has large baskets of crickets and cockroaches for sale. Someone comes up and picks out a few tarantulas while I am there and pays for them. How do you choose a good tarantula? How do you know if you got a bad one? This is an important question. My roommate and I pitch in 1000 riel (about 25 cents) each to buy one. I suspect we got ripped off big time, paying inflated tourist prices for our tarantula, but what are you going to do? After a lot of posing for photographs I got ready to eat it. The funniest photograph is the one with an intense look of concentration on my face as I hold it up to my nose to sniff it. Doesn't everyone smell unfamiliar food before tasting? It didn't smell bad, so I bit off one of the legs. There was an encouraging lack of gooey spider guts oozing out of it, so I ate the leg. It tasted like deep-fried anything.

My room mate and I shared the "drumsticks" with other brave souls and then it was time to board the buss again. I tried biting the carapace, but it was kind of hard. And it was a spider, now mostly legless, as big as my palm. I asked the bus conductor if "I eat all?" and he indicated yes, so I tried another bite. My teeth broke through the outer shell to the roasted insides of the spider. It tasted kind of like paté. I don't like paté much. I didn't finish it. I shouldn't have spoiled my appetite with the lunch box. But I can now authoritatively tell you whether any foodstuff I sample tastes better or worse than tarantula ass.

Lots of drumsticks

The conductor made an announcement on the bus PA, but between his accent and the speakers it was completely unintelligible. My seatmate got up and went to the front and next thing we know she's on the PA with a clear English translation of the first PA, historical and cultural details of the scenery we're passing. We finally made it all the way back to Phnom Penh.

I go out for dinner with a small group of interesting group members, at a restaurant where they train street kids to work in the hospitality industry. It's an adventurous menu of interesting food, including a tarantula-based appetizer. "Are you going to get that?" the table asked me, apparently the designated point person for weird food now.

"No," I said, knowing this may be the only time in my life I have a chance to use this line, "I had tarantula for lunch." I had stir fried ants for dinner instead. Really good, but I've had tangier ants. I like my ants tangy.

From the balcony of the restaurant I observed and documented this, which I presume was the electrical connection of the building to the grid. Electrical standards in Cambodia, if there were any, were low. Below is a fairly typical power pole with electrical transmission wires. There was another one down the street with a tree all stuck inside it, but I don't think that photo worked out.
